Ch 12: DNA Replication - Processes and Steps: Tutoring Solution

About This Chapter

The DNA Replication: Processes and Steps chapter of this High School Biology Tutoring Solution is a flexible and affordable path to learning about DNA replication. These simple and fun video lessons are each about five minutes long and they teach all of the processes and steps in DNA replication required in a typical high school biology course.

How it works:

  • Begin your assignment or other high school biology work.
  • Identify the DNA replication concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our high school biology tutoring solution will benefit any student who is trying to learn about the processes and steps in DNA replication and earn better grades. This resource can help students including those who:

  • Struggle with understanding dispersive models, DNA double helix and helicase processes, DNA polymerase, RNA primase, leading and lagging strands or any other DNA replication topic.
  • Have limited time for studying
  • Want a cost effective way to supplement their science learning
  • Prefer learning science visually
  • Find themselves failing or close to failing their DNA replication processes and steps unit
  • Cope with ADD or ADHD
  • Want to get ahead in high school biology
  • Don't have access to their science teacher outside of class

Why it works:

  • Engaging Tutors: We make learning about DNA replication processes and steps simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live biology tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about DNA replication processes and steps on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning Objectives

  • Become familiar with the conservative, semi-conservative and dispersive models of DNA replication.
  • Explain how DNA helicase takes apart the DNA double helix in preparation for replication.
  • Describe how DNA replication is initiated by DNA polymerase and RNA primase.
  • Explain the role of the leading strand and DNA polymerase activities in DNA replication.
  • Discuss how replication bubbles are formed during DNA replication.

What Is DNA Replication? - Conservative, Semi-Conservative & Dispersive Models

1. What Is DNA Replication? - Conservative, Semi-Conservative & Dispersive Models

How do we know that DNA replication is semi-conservative? How do we know it's not conservative or dispersive? Let's follow the famous experiment by Meselson and Stahl to find out!

How Helicase Unwinds the DNA Double Helix in Preparation for Replication

2. How Helicase Unwinds the DNA Double Helix in Preparation for Replication

How does semi-conservative replication begin? Discover how DNA helicase creates a replication fork to unwind the complicated DNA molecule and allow daughter strands to form on the parental template.

How DNA Polymerase and RNA Primase Initiate DNA Replication

3. How DNA Polymerase and RNA Primase Initiate DNA Replication

How do enzymes assist in starting DNA replication? In this lesson, we explore the work of a contributing enzyme, DNA polymerase, and learn how the RNA primer is made by the action of RNA primase.

DNA Replication: The Leading Strand and DNA Polymerase Activities

4. DNA Replication: The Leading Strand and DNA Polymerase Activities

How does replication occur in the antiparallel DNA molecule? In this lesson, explore the significance of the leading and lagging strands, and learn how Okazaki fragments and RNA ligase make DNA replication possible.

DNA Replication: Review of Enzymes, Replication Bubbles & Leading and Lagging Strands

5. DNA Replication: Review of Enzymes, Replication Bubbles & Leading and Lagging Strands

Feeling lost in the thorny details of DNA replication? This lesson provides an overview of semi-conservative replication, with a focus on putting together all of the concepts involved. We'll review the work of each enzyme on our way to completing the big picture of DNA replication.

Non-Coding Regions of DNA: Sequences & Explanation

6. Non-Coding Regions of DNA: Sequences & Explanation

In biology we learn that DNA is the blueprint for life. However, 98% of your DNA does not code for proteins. This non-coding DNA has been called useless, worthless, in a word, 'junk DNA.' But is it really worthless? Read this lesson and find out.

Replication Bubble: Definition & Overview

7. Replication Bubble: Definition & Overview

A replication bubble is the setting for DNA replication. In this lesson, we will review DNA, then find out why replication bubbles are called a bubble, what stabilizes them and how DNA polymerase finishes up.
